Racers can't win what they don’t finish. That’s why AMSOIL formulators built DOMINATOR® 2-Stroke Racing Oil. This complex blend of oils and additives directly addresses the heat, pressure and friction of race-engineered engines. These engines operate on the edge, yet engine reliability is critical. DOMINATOR does an outstanding job protecting high-performance engines. It adds durability that professional racing teams depend on and delivers confidence so engines can be pushed to the limit.

During the Pro Open final at the opening rounds of AMSOIL Championship Snocross, professional rider Lincoln Lemieux's Ski-Doo lost all its engine coolant after a hose clamp broke. Despite intense heat that melted the exhaust power valve covers, O-rings and gaskets, AMSOIL DOMINATOR Synthetic 2-Stroke Racing Oil protected Lemieux's engine so well, the team is able to reuse the engine after replacing the melted parts.

Excellent Lubricity and Film Strength
High-performance and race-designed two-stroke engines operate under severe
conditions. They are modified for higher compression ratios, higher rpm and leaner
combustion, all of which increase heat and pressure. High heat can quickly burn
off light oils and cause rapid piston expansion, decreasing piston-to-cylinder
wall clearances and increasing the likelihood of piston scuffing and seizure.
High pressure can exceed the film strength of low-viscosity oils, which promotes
crankshaft bearing wear and pitting.

DOMINATOR is purpose-built for outstanding film strength and lubricity. It is
engineered with carefully selected, higher-viscosity synthetic base oils to withstand
the high heat and pressure common to high-performance and racing applications.
DOMINATOR’s anti-friction chemistry is race-proven to provide an extra measure of
protection against piston scuffing and bearing wear.

Outstanding Cleanliness
The oil and fuel burned in the two-stroke combustion process leave destructive
deposits on the pistons, rings and in the combustion chamber. Excessive deposits
can lead to catastrophic engine problems, including ring sticking, exhaust port
blocking and pre-ignition.

RACING IS RESEARCH™
During the opening weekend of the 2015/16 AMSOIL Championship Snocross season, professional rider Lincoln Lemieux's
Ski-Doo* RS600 suffered a broken hose clamp, allowing the coolant to pump from the system. The intense heat that resulted
melted the exhaust power valve covers, O-rings and engine gaskets. DOMINATOR Synthetic 2-Stroke Racing Oil, however,
delivered exceptional protection despite the severe conditions. The rings and pistons were still free and the crankshaft turned
freely. Scheuring Speed Sports is able to reuse the engine after repairing the melted parts, providing concrete testimony of
DOMINATOR's superior performance.

Applications
Use in high-performance stock or modified two-stroke engines,
including air- or liquid-cooled snowmobiles, personal watercraft,
motorcycles (moto X), ATVs, go-carts and outboard motors**.
Good for use with coated or non-coated pistons, high-octane
racing fuels and exhaust power valves. Compatible with most
other two-stroke oils; however, mixing oils should be minimized.

Use in oil-injected and pre-mix applications that require API TC
oils. In pre-mix applications, DOMINATOR delivers outstanding
protection at 50:1 (2.6 oz. oil per U.S. gallon of gas), although
many racers modify the mix ratio to suit their setup. Not suitable
for use with alcohol or nitro-methane fuels.

** Not suitable for long-term use in outboard motors as a TC-W3-type oil, although excellent as a race oil for short-term use where motors are periodically inspected.
